I did promise I’d reveal the secret of the mystery this week, I’m afraid it’s much more prosaic than you might wish. I recognised the curtains from a previous prompt.I had looked through that window before and was completely trapped by the oscillation between the story I wrote for that prompt (https://neilmacdonaldauthor.wordpress.com/2016/06/29/friday-fictioneers-the-fury/) and the need to write something new. The last line of both stories is the same.
